I just now realized that you posted the link to your own thread.
I have answered there
Kind regards

In theory, there is no difference between theory and practice. But, in practice, there is.

I think it's not worth making an EPROM programmer. A new one for 8-bit EPROM is worth around € 30 on ebay.
I have this (G540):

But this other one I think still works better and cheaper (TL866CS):

But they don't burn 25 and 27 volt Eprom.

He-He mine does, well 21 and 25v 8-)

@Charlie

If the idea interests you Charlie I could bring mine along on Saturday if you fancy copying it.

Works on both zeddy and speccy although I only have the speccy software. :(

it just bothers me that i have 2 great programers that can burn anything but are useless without the software. these programers can burn 4 eproms at a time.... i wish wish wish one of you guys had the software.

searching the internet turned up nothing aside from one site for the sunshine machine... but that software didnt work for one reason or another. what a shame.

the fairy yl23 can also test other chips... but missing software makes it anice door stop.
